'- CHURN-OPERATING MECHANISM.

Application fi-led October 30, 1924. Serial No. 16,905.

I To allwhom it may concern:

Be it known that I, W'ILLIA J. Wnsr, a citizen of the United States, residing at El Paso, in the county of WVhite and State of- Arkansas, have invented certain new'anduseful Improvements in Churn-Operatlng Mechanism,- of. which the following is a specification.

This invention relates to improvements in mechanism for operating churns, and for like purposes, and has for one of its objects to simplify and improve the construction of devices of this character.

WVith these andother objects in view the invention consists in certainnovel features of construction as hereinafter shown anddescribed and then'specifically pointed out in the claims, and in the drawingsillustratiVe of the preferred embodiment of themvention. j

F lgure 11s a front elevatlon, and- Figure 2 is a side elevation,iofthe im-.

' by serews12 or the like, and formed with an integral head portion 13 and vertical web Extending from, the web 14 is a stud 15 upon which a relatively large drive wheel 16 is journaled. i

The hub 17 of the Wheelis provided with a plurality of apertures 18 spacedat varying distances from the shaft 15 to receive. a crank pin, indicated at 19, and which is preferably extended into a handle 20, and by which thewheel may be manually r0- tated.

-An electric motor, indicated conventionally at 21, is mounted on. the head portion 13, and having a belt .pinion 22 in vertical alinement with the wheel 16, and over which a drive belt 23 operates. j

By this arrangement the wheel 16 may be actuatedeither manually. or by the motor, as preferred. l

Extending from the base member 11 are brackets 24 and 25, and ,terminatingrespectively in bearings 26 and 27. r

' Slidablydisposed through the bearing 26 is a rod 28, and slidably disposed through body b I any'suitable material.

.the bearing 27 is tubular member 29, the rod 28 being rigidly connected to the upper end of the tubular-member 29.

Adjustably coupled to the rod 28 is a cross head member 29 and'provided with a set screw 30 to enable the cross head member to be adjusted upon the rod.

The n1ember29 is formed with oppositely extending studs 31, 32'to which spaced con-- necting rods 33 and 34; are journalled at their lower ends and with their upper ends journalled on the combined crank pin and handle 19, 20. i

The bracket 25 is curved as shown in Fig ure 3 to avoid the rod 33. i

The improved device may be employed for operating various mechanical devices, but for the purpose of illustration is shown applied to a conventional churn, the churn eing represented conventionally at 35 the dasher at 36, and the dasher red at 37, the latter received at its upper end in the sleeve member 29, and adjustably coupled thereto by a set screw 38.

By this simple arrangement it will be obvious that when the wheel 16 is rotated either manually by power applied to the handle 20, or by a motor 21, the churn dasher rod will be correspondingly operated.

By arranging the dasher rod 37 to be ad justably coupled to the sleeve 29, the posi tion of the dasher 36 may be correspondingly adjusted relative to thechurn body and the depth of the cream therein, and by providing the hub 17 of the wheel 16 with-a plurality'of the apertures 18 for the crank pin 19 spaced at varying distances from the shaft-'15, the throw of the dasher can also be varied, as requiredto correspond to the condition or quantity of the cream.

The improved deviceis simple in construction and can'be inexpensively manufactured, and of any size or capacity, or of The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages. i

Having thus described the invention what is claimedis: I

1. In an apparatus of the class described,

a stationary support, a drive Wheel mounted on said support and having a plurality of apertures spaced at varying distances from the center of the wheel, a crank pin alternately insertible in the apertures of said drive Wheel spaced brackets extending from said support and each including a bearing, a rod movable through said bearings and adapted to be coupled to the device to be reciprocated, a cross head member adjustably coupled to said rod and having studs extending "from its opposite ends, and connecting rods journalled at one end respeetively upon said studs and journalled at their other ends to said crank pin.

2. In an apparatus of the class described, a stationary support, a drive Wheel mounted on said support and having a plurality of apertures spaced at varying distances from the center of the Wheel, a crank pin alternately insertihle in the apertures of said drive Wheel, spaced brackets extending from said support and each including a bearing, a rod movable through one of said bearings, a sleeve member movable through the other of said bearings and connected to said rod, means for adjustably coupling said sleeve to the device to be reciproeated, a cross head member adjustably coupled to said rod and having studs extending from its opposite ends, and connecting rods journalled at one end respectively upon said studs and journailed at their other ends to said crank pin.

In testimony whereof, I ElffiX my signature hereto.
